Lidded pet dish
View Patent ↗A lidded pet food dish uses wireless technology to independently and selectively open one of a plurality of lidded food compartments for access by a pet. The dish discriminates between pets by means of a tag worn by each pet to allow or prevent access to a given food compartment. Electronic circuitry for this functionality is operable by any wireless technology and provides for manual system override by the pet owner as well as remote control capability.
1. A pet dish comprising:
at least one pet food compartment,
a lid for covering the at least one pet food compartment,
means for moving the lid to uncover the at least one pet food compartment,
at least one tag worn by a pet,
a sensor to wirelessly scan for and identify the at least one tag when the pet and tag enter a defined area about the dish, the sensor being capable of increasing and decreasing its scan frequency, and
an electronic circuit for actuating said lid moving means when said sensor identifies said tag and for moving the lid to cover the at least one pet food compartment when the pet and tag leave the defined area,
wherein the sensor increases its scan frequency when the lid is moved to uncover the at least one pet food compartment, and
wherein the sensor reduces its scan frequency when the lid is moved to cover the at least one pet food compartment.
2. The pet dish of claim 1 wherein the sensor and the at least one tag are operable by wireless transmission and/or detection of radio frequency radiation.
3. The pet dish of claim 1 wherein the sensor and the at least one tag are operable by wireless transmission and/or detection of infrared radiation.
4. The pet dish of claim 3 wherein a separate sensor is provided for each tag and its corresponding food compartment.
5. The pet dish of claim 1 wherein the lid is rotatably movable about a hinge.
6. A pet dish comprising:
two or more pet food compartments,
a lid for covering each of the two or more pet food compartments,
means for moving the lids to selectively and independently uncover each of the two or more pet food compartments,
two or more tags each tag being worn by a pet,
a sensor to wirelessly scan for and identify the two or more tags when the pets and tags enter a defined area about the dish, the sensor being capable of increasing and decreasing its scan frequency, and
an electronic circuit for actuating said lid moving means when said sensor identifies said tags and for moving the lids to cover each pet food compartment when the pet and tag leave the defined area,
wherein the sensor increases its scan frequency when one or both of the lids is moved to uncover a pet food compartment, and
wherein the sensor reduces its scan frequency when one or both of the lids is moved to cover a pet food compartment.
7. The pet dish of claim 6 wherein the sensor and the two or more tags are each operable by wireless transmission and/or detection of radio frequency radiation.
8. The pet dish of claim 6 wherein the sensor and the two or more tags are each operable by wireless transmission and/or detection of infrared radiation.
9. The pet dish of claim 8 wherein a separate sensor is provided for each tag and its corresponding food compartment.
10. The pet dish of claim 6 wherein the lid is rotatably movable about a hinge.
11. A pet dish for use by a plurality of pets comprising:
a plurality of pet food compartments,
a lid for covering each of the pet food compartments,
means for moving each of the lids to selectively and independently uncover each of the plurality of pet food compartments,
a tag being worn by each of the plurality of pets,
a sensor to wirelessly scan for and identify each tag when the pet wearing that tag enters a defined area about the dish, the sensor being capable of increasing and decreasing its scan frequency, and
an electronic circuit for actuating said lid moving means when said sensor identifies the tag and for moving the lid to cover the corresponding pet food compartment when the pet and tag leave the defined area,
wherein the sensor increases its scan frequency when a lid is moved to uncover one of the plurality of pet food compartments, and
wherein the sensor reduces its scan frequency when a lid is moved to cover one of the plurality of pet food compartments.
12. The pet dish of claim 11 wherein the sensor and each tag is operable by wireless transmission and/or detection of radio frequency radiation.
13. The pet dish of claim 11 wherein the sensor and each tag is operable by wireless transmission and/or detection of infrared radiation.
14. The pet dish of claim 13 wherein a separate sensor is provided for each tag and its corresponding food compartment.
15. The pet dish of claim 11 wherein each lid is rotatably movable about a hinge.
